Application filed December 3, 1914. Serial No. 87-55,

To all whom it may concern:

Be it known that I, Encnnn Van Horn, a citizen of the United States, and a resident of the borough of Manhattan, city, county,

and State of New York, have invented a itself is manufactured but before the ends of the tube are connected together. My device is adapted to turn back the ends of the tube upon the same, after which one of the ends of the tube is again returned upon itself. When the tube is in this condition, namely, one end lapped upon itself forming one fold and the other end lapped upon itself and returned forming two folds, the exposed laps may be treated with cement or other securing material and the single lap end is lapped over the exposed surface of the double lap end, and the two ends of the tube are then vulcanized or otherwise secured in any. of the well-known ways. After the ends of the tubes are securely Vulcanized or otherwise fastened to each other, the lap remaining in the tube is pulled out manually leaving the finished product consisting of a continuous annular tube.

Referring now to the drawings: Figure 1 is a vertical section of my device showing a tube in place ready to be lapped; Fig. 2 is a vertical section of my device showln g a tube in the process of being lapped; Fig. 3 1s a cross section on the line 33 of Fig. 2, showingthe cross-head and a tube in the process of being lapped in the background. Fig. at

' is a cross section on the line H of Fig. 1;

Fig. his a cross section on the line 5'5 of Fig. 2; Fig. 6 1s a cross section on the line (36 of Fig. 1; Fig. 7 is an illustration of my preferred form of mandrel; Fig. 8 shows the lapping of the ends of the tube preparatory to their being prepared for connection; Fig. 9 illustrates the tube after the ends thereof have been prepared for connection with the single lap of one end of the tube and the double lap of the other end of the tube in position; Fig. 10 illustrates the tube after the ends thereof have been secured in position and the remaining laps pulled out.

Referring now in to these drawings 1 represents a table supported by a su... able pedestal 2, on which table is adapted to s'de a cross head support 3, which supports cross-head st; this cross-head is prov with a threaded portion which is adapted to adjust radially the band plates through the eciiperation of the lugs t con nected to the band plates and extending into the grooves of the threaded portion l. Mounted on the pedestal 52 is also a support 5, on which is mounted the casing 6. in this casing is mounted an adjustable slide 7 held against rotation in the tracks 8 by means of lugs 9, attached to the said slide. This slide 7 is manipulated by means of the screw 10 which is integrally connected to the adjustin handle 11, mounted on the pivot 19.. Attached to the slide 7, at one end, are toggle-s 13, which are connected at the other end thereof to the vanes 1%. These vanes are cut away intermediate their ends forming the recesses 14: therein. On the rear ends of the projecting portions of these vanes being the ends farther away from the adyusting handle 11, are T-headsll), the function of which will be herein described. The vanes 14: are adjustably mounted in a supporting r rod 16, being adapted to slide radially there in by means of the coliperation of 17 in the vanes and pins 18 in the supporting rod 16. have shot -i in the drawings four of these vanes, but of course any 1.111111" ber of vanes may be used.

Connected with the band plates are the forward ends of bands connected at 20 to the rear Theads 15 of the vanes lti:

and the rear if-heads 15 of the vanes 1a;

RHEC- v The said vanes during such operation being held in the contracted position with reference to the rod 16 so that the tube may be readily drawn thereon without unnecessary friction. After the tube has been so drawn on the rod and vanes, and is in the desired position the slotted mandrel 2-1 drawn over the tube to a point near the end thereof desired to be lapped. The handle 11 is then manipulated so 'as to draw toward itself the slide 7, the connected toggles 13, and the vanes ll. In the travel of the said vanes the slots 17 therein cooperate with the pins 18 of the rod 16 and thus expand the vanes with reference to the supporting rod 16. It will be noted that the vanes 14: are cut away intermediate their length-so as to effect engagement with the tube only at their rear ends. When the handle 11 has been sutlicien'tly n'ianipulated the vanes let will be expanded so as to engage the inner walls of the tube 21 and hold the same in rigid position. The handle of the crosshead 4 may then be revolved so as to eli'ect the radial movement of the band plate 1* to adjust the same into the desired position. The tube is now in position to be turned'or lapped. In order to accomplish this the cross-head 4 is manually drawn back and the flexible bands 19 turn the end of the tube over the mandrel 2%, which slides back over the tube until the desired lap of the tube is accomplished' This is clearly shown in Fig. 2. When the desired lap has beeneliected the handle 11 is manipulated to release the vanes 14 and the mandrel and tube in its lapped condition are then withdrawn from the device. The

other. end oi? the tube is then treated in the 1 tending laterally from the outer longitudisame way so as to obtain the desired lap. In order that,suiiicient cementing or vulcanizingsurface may be exposed for treatment it will be seen that the end of the tube which is a; receive the double lap will be lapped over on the machine a distance about twice that oi. the single lap end. The lapped portion of this end is then lapped back again on itself the latter lapping being performed by hand after the tube has been removed from the machine. To facilitate the turning back by hand of the final lap of the double lapped end I have provided recesses 23 in the mandrel Al so that the end of the tube may be readily taken between the thumb and ,iinger thus enabling the'operator to obtain a proper grip on the same. After both ends of the tube ha ve been prepared in the manner indicated they are brought together as show-n in Fig. 8, the double lapped end .t'orming a male member and the single lapped end 'hn'ming a female mcmherl The exposed, surfaces of the laps are then treated for vulcanization or other method of connection, and the female lap is then drawn over the exposed suriace ot' the male lap as shown in Fig. 9. The ends of the tube are end of said cylinder for the purpose of facilitating the handling of tubes thereon.
